Azure RDMA drivers for H-Series running updated kernel with TCP SACK vulnerability fix

Hi,

Due to CVE-2019-11477, CVE-2019-11478 & CVE-2019-11479, we need to upgrade the kernel on H-Series RDMA VMs running the CentOS 7.4 HPC image.

Unfortunately, we haven't been able to figure out if the RDMA drivers for H-Series are automatically set up by WAAGENT for newer kernel versions ?

If not, is it possible for us to manually compile msft-rdma-drivers for H Series machines on Azure ?

An issue has been raised with the LIS team about this as well. [https://github.com/LIS/lis-next/issues/722](url)

Thanks.

No files or tests are identified. Start by reviewing WALinuxAgent behavior for H-Series RDMA VMs using the CentOS 7.4 HPC image, then read the linked LIS issue 722. Determine whether updated kernels automatically set up the msft-rdma-drivers or whether supported manual compilation is required.
